Wireless communication system and method

Technical field

The present invention relates to be used for the method and apparatus of wireless communication system, particularly relate to the wireless communication system, the method and apparatus that comprise Control Node, intermediate node and destination node.

Background technology

Because the number of wireless device constantly increases and the demand of wireless device is constantly increased the wireless communication system sustainable development.For satisfying ever-increasing demand, wireless provider has disposed the more wireless launcher of more number.Yet wireless provider also utilizes the alternative system based on relaying (relay-based) that can be used as.

In the system based on relaying, a node of wireless system can use another node communication in one or more intermediate nodes (being called via node) and the wireless system.In some systems, via node can be described as relay station, and can be described as transmission path with node between the node of destination with the combination that is connected at source node.All possibly have system in the wireless network of any kind based on relaying.

Instance based on the system of relaying is multi-hop relay (multi-hop relay, MR) network.Fig. 1 is based on institute of electrical and electronic engineers (Institute of Electrical and ElectronicsEngineers, the IEEE) figure of the exemplary prior art MR network 100 of 802.16 series standards.

As shown in Figure 1; MR network 100 (for example can comprise one or more reflectors; Base station (basestation; BS)) 110, one or more relay station (relay station, RS) 120 (comprising RS 120a, 120b and 120c) and one or more subscriber station (subscriber station, SS) 130 (comprising SS130w, 130x, 130y and 130z).

In MR network 100, can use one or more relay stations (for example RS 120a, RS 120b, RS120c etc.) to realize communicating by letter between reflector stations (for example BS110) and the subscriber station (for example SS130w, SS130x, SS130y, SS130z etc.).For instance, in MR network 100, RS120a can receive data and data are sent to another relay station (for example RS120b) from BS110.Perhaps, RS 120a can receive data from subordinate relay station (for example RS120b), and sends it to BS110.As another instance, RS120c can receive data from RS120b, and data are sent to the subscriber station (for example SS130w) of support.Perhaps, RS120c can receive data from subscriber station (for example SS130w), and sends it to main relay station (for example RS120b).

For example some embodiment of MR network 100 can use dispatching algorithm, and subscriber station (for example SS130w, SS130x, SS130y, SS130z etc.) comes the initial network (that is the telecommunication network that, in scope, is provided to subscriber station by BS110) that gets into by said dispatching algorithm.In case accomplish the initial network that gets into, BS110 can distribute access port so.In other embodiments, can be in each frame period the dynamic assignment access port.Under above any situation, all can enlarge or reduce access port, but access port still is assigned the station to the specific user, has got rid of other subscriber station whereby and has used said access port.

Fig. 2 explains and uses the multiple acquisition of orthogonal frequency division (Orthogonal Frequency-DivisionMultiple Access; OFDMA) exemplary media access control (Media Access Control, MAC) frame format based on I EEE 802.16 system standards.As shown in Figure 2, can be divided into the subframe of variable-length the transmission time: up link (uplink, UL) subframe and down link (downlink, DL) subframe.Although detailed icon not, UL subframe can comprise range channel (ranging channel), (channel quality information channel is CQICH) with the UL data set that contains data for channel quality information channel.

The DL subframe can comprise preamble, frame control header (Frame Control Header, FCH), DL-MAP, UL-MAP and DL data set zone.Preamble can be used for being provided for synchronous reference.For instance, preamble can be used for regulating timing off-set, frequency shift (FS) and power.FCH can contain the frame control information that is useful on each connection, for example comprises the decoding information that is used for SSs130.

DL-MAP and UL-MAP message can be down link respectively and uplink communication distributes the passage access.That is to say that DL-MAP message can provide the catalogue of access port position in current downlink subframe, and UL-MAP message can provide the catalogue of access port position in current uplink sub-frames.In DL-MAP message, this catalogue can be taked the form of one or more DL-MAP information elements (MAP InformationElement, MAP IE).Each MAP IE in the DL-MAP message can contain the parameter that is useful on single connection (that is, with single SS130 be connected).These parameters be used in recognition data group in the current subframe be where be positioned at, identity and one or more transmission parameter of the set reception of the length of data set, data set.

For instance, each MAP IE can contain: and connection ID (connection ID, CID), its recognition data group is hoped the destination device (for example, SS130w, SS130x, SS130y, SS130z etc.) of arrival; Use between downlink region code (Downlink Interval Usage Code, DIUC), its expression can be defined between the downlink region of downlink transmission and use code; The OFDMA symbol offset has the skew of the OFDMA symbol that data set begins in its indication; The subchannel skew, its indication is used to carry the lowest index OFDMA subchannel of data set; Or the like.Also other parameter be can comprise among the MAP IE, the parameter, indication number of subchannels purpose parameter of rising parameter, indication OFDMA number of symbols etc. for example comprised.Use like this paper, prior art MAC header can be described as with MAP IE and is connected the switching controls data.

DL-MAP and UL-MAP message can respectively have been followed the data set zone.The data set zone can comprise one or more data sets.Can each data set in the data set zone modulated and encode according to the control types of corresponding connection switching controls data.For instance; Referring to Fig. 3, MAP IE " w " can provide the control information of data set " w ", and MAP IE " x " can provide the control information of data set " x "; MAP IE " y " can provide the control information of data set " y ", and MAP IE " z " can provide the control information of data set " z ".

Referring to Fig. 1, BS110 can receive the data set of SS130w, SS130x, SS130y and SS130z once more, and each said SS130 is the user's set of RS120c.BS110 can produce the connection switching controls data of each SS130, thereby will connect in the DL MAP IE mouth of switching controls data insertion frame.BS110 can insert the sets of relational data of each SS130 corresponding to each and connect in the data set zone of switching controls data.BS110 can be transferred to first node with frame along transmission path, i.e. RS120a.RS120a can receive data, and handles each and connect switching controls data to determine whether that any data are expectation user's sets of arriving RS120a.If wherein having no data is expectation user's sets of arriving RS120a, RS120a can forward the data to next RS120 along transmission path so.In this example, having no data is expectation user's sets of arriving RS120a, and RS120a can be with transfer of data to RS120b.

Likewise, RS120b can receive said data, and handles each control data to determine whether that any data are expectation user's sets of arriving RS120b.If wherein having no data is expectation user's sets of arriving RS120b, RS120b also can forward the data to next RS120, i.e. RS120c along transmission path so.RS120c can receive said data, and handles each control data to determine whether that any data are expectation user's sets of arriving RS120c.In this example, SS130w, SS130x, SS130y and SS130z are the user's sets of RS120c, and RS 120c can handle and connect the switching controls data, thereby according to the transmission parameter that is stored among the MAP IE proper data are forwarded to each SS130.

In MR network 100, but in each RS120 processed frame of transmission path each connects switching controls data (for example, MAC header and MAP IE), till indivedual control datas and its destination of related data arrival thereof.Therefore, for example each connection switching controls data of Fig. 1 were handled through three times before arriving its destination possibly.This possibly cause a large amount of uses and the corresponding transmission latency of system resource.

Figure 11 is explanation figure from the exemplary communication of BS110 in label handover network 400.Shown in figure 11, network 400 has been expanded to comprise RS420d, 420e and 420f and SS430s, 430t, 430u and 430z.In an example embodiment, BS110 can store one or more BS label forms 440.Said one or more BS label form 440 can comprise the data that are associated with one or more via nodes, one or more transmission path and/or one or more transmission path identifier.Shown in figure 11; BS label form 440 can be discerned six transmission paths: transmission path 1 (that is the transmission path from BS410 to RS420a), transmission path 2 (that is the transmission path from BS410 to RS420b), transmission path 3 are (promptly; Transmission path from BS410 to RS420c), transmission path 4 (promptly; Transmission path from BS410 to RS420d), transmission path 5 (that is the transmission path from BS410 to RS420e) and transmission path 6 (that is the transmission path from BS410 to RS420f).

In addition, BS label form 440 can be discerned the relation between one or more transmission paths and the one or more SS430.For instance, BS label form 440 can be identified as SS430t (that is, " t ") by means of transmission path 1 and communicate; With SS430u (promptly; " u ") be identified as by means of transmission path 2 and communicate, SS430w, 430x and 430y (that is, " w ", " x " and " y ") are identified as by means of transmission path 3 communicate; And SS430z (that is, " z ") is identified as by means of transmission path 6 communicates.In addition, BS label form 440 can indicate SS430 just to communicate by BS410.Although BS label form 440 shows that the service that offers SS430 does not have repetition or overlapping, possibly can receive service by means of a plurality of transmission paths by single SS430.For instance, SS430y can receive service from RS420c and RS420f, so SS430y can be associated with the transmission path that arrives RS420c and RS420f.Represented like Figure 11, " y " not only will appear at (shown in BS label form 440) in the row identical with " 3 ", but also will appear in the row identical with " 6 " (not shown).

In an example embodiment, each RS420 can store one or more RS label forms 450.Because RS420a is the domination RS420 of RS420b, RS420c, RS420e and RS420f; Therefore and be in the transmission path that arrives among the said subordinate RS420 each; So RS label form 450a can (for example) discern four transmission paths: transmission path 2 (that is, arriving the transmission path of RS420b), transmission path 3 (that is, arriving the transmission path of RS420c), transmission path 5 are (promptly; Arrive the transmission path of RS420e) and transmission path 6 (that is, arriving the transmission path of RS420f).In addition, RS label form 450a can indicate SS430t to be served by RS420a.Because RS420b is the domination RS420 of RS420c and RS420f; Therefore and be in the transmission path that arrives among its subordinate RS420 each; So RS label form 450b can discern two transmission paths: transmission path 3 (promptly; Arrive the transmission path of RS420c) and transmission path 6 (that is, arriving the transmission path of RS420f).In addition, RS label form 450b can indicate SS430u to be served by RS420b.The RS label form 450c of RS420c possibly not contain any transmission path information, because RS420c does not have any subordinate RS420.Yet RS label form 450c can indicate SS430w, SS430x and SS430y to be served by RS420c.Similarly, the RS label form 450f of RS420f possibly not contain any transmission path information, because RS420f does not have any subordinate RS420.Yet RS label form 450f can indicate SS430z to be served by RS420f.RS420d and RS420e possibly not have RS label form 450 or in its RS label form 450, do not have data, because RS420d and RS420e do not have subordinate RS420 and to any SS430 service be not provided.

In the instance of Figure 11, BS410 can receive the data that are used for SS430s, SS430t, SS430u, SS430w, SS430x, SS430y and SS430z.But BS410 access BS label form 440 to be confirming to be used for the transmission path of each SS430, and can be each transmission path and produce label and switch MAP IE.In addition, BS410 can be each SS430 that receives data and produces connection switching controls data.BS410 can be placed in the data set zone connecting the switching controls data, and can the label switching controls data that be associated be placed in the frame MAP IE groove, in the MAC header or in these two.For instance, referring to the Frame between BS410 and the RS420a 460, BS410 can send the frame that contains four label switching controls data, and each label switching controls data is associated with a data set zone of frame.That is to say; Label switching controls data 1 can be corresponding to data set zone t; Label switching controls data 2 can be corresponding to data set zone u, and label switching controls data 3 can be corresponding to data set zone wxy, and label switching controls data 6 can be corresponding to data set zone z.In case BS410 accomplishes the processing to frame, BS410 just can be transferred to the next node in the transmission path, i.e. RS420a with frame.

But RS420a receiving data frames 460, and can handle each label switching controls data.In this example, Frame 460 can contain four label switching controls data.The label identification RS420a that RS420a can confirm to contain in the label switching controls data 1, and the connection switching controls data among the t of RS420a decodable code data set zone.RS420a can arrive SS430t according to the related data transmission that connection switching controls data parameters will be included among the t of data set zone equally.

RS420a can confirm that label switching controls data 2,3 and 6 do not expect to be used for RS420a, and RS420a can use the label that in label switching controls data, finds to come access RS label form 450a, so that for each confirms the next node in the transmission path.In this example, RS420a can confirm that RS420b is a next node, and RS420a can be forwarded to RS420b as Frame 470 with remaining frame data.Yet, if RS420a confirms next node not in the transmission path of RS420a, the discardable frame of RS420a so.For instance, RS420a can forward the data to RS420b and RS420e, and abandons the data that the destination is RS420d.

But RS420b receiving data frames 470, and can handle each label switching controls data.In this example, Frame 470 can contain three label switching controls data.The label identification RS420b that RS420b can confirm to contain in the label switching controls data 2, and the connection switching controls data among the u of RS420b decodable code corresponding data group zone.RS420b can arrive SS430u according to the related data transmission that connection switching controls data parameters will be included among the u of data set zone equally.

RS420b can confirm that frame control data 3 and 6 do not expect to be used for RS420b, and RS420b can use the label that in label switching controls data, finds to come access RS label form 450b, to confirm the next node in the transmission path.In this example, RS420b can confirm that RS420c is the next node corresponding to the frame data of control data 3, and RS420f is the next node corresponding to the frame data of control data 6.RS420b can be forwarded to RS420c as Frame 480 with the frame data corresponding to control data 3, and can the frame data corresponding to control data 6 be forwarded to RS420f as Frame 490.Yet, if RS420b confirms next node not in the transmission path of RS420b, the discardable frame of RS420b so.For instance, RS420b can forward the data to RS420c and RS420f, and abandons the data that the destination is RS420d and RS420e.

But RS420c receiving data frames 480, and can handle each label switching controls data.In this example, Frame 480 can only contain label switching controls data.The label identification RS420c that RS420c can confirm to contain in the label switching controls data 3, and the connection switching controls data among the wxy of RS420c decodable code data set zone.The related data transmission that RS420c can will be included in according to the connection switching controls data parameters of each SS430 among the wxy of data set zone equally arrives SS430w, SS430x and SS430y.

Similarly, but RS420f receiving data frames 490 and handle each label switching controls data.In this example, Frame 490 can only contain label switching controls data.The label identification RS420f that RS420f can confirm to contain in the label switching controls data 6, and the connection switching controls data among the z of RS420f decodable code data set zone.RS420f can arrive SS430z according to the related data transmission that connection switching controls data will be included among the z of data set zone equally.

In this way, network 400 can use one or more via nodes to transmit by replacing one or more connection switching controls data with one or more label switching controls data and receive data.
